What do you mean by "banding with light effects"? Like when light effect also effecting objects? In that case you just need to adjust the Z coordinate (Cmd+[ and Cmd+] keys, or rearranging objects on the left hand side panel on the object list)
Thanks trudnai, but I didn't refer to that. Colour banding is a problem of inaccurate colour presentation in computer graphics. The effect is not smooth. I want it to look like the example on the right. But I simply can't achieve it with the lights in Buildbox. Only with lights that use 100% opacity it seems to be accurate. But when I want a light which is much more soft (5-50% opacity) I get the banding right away.
